Application filed January 15, 1920. Serial No. 351,960.

To all whom it may concern Be it known that I, Oirnn A. Genius, a citizen of the United States, and a resident of Needham, in the county of Norfolk and Commonwealth of ldassachusetts, have invented certain new and useful improvements in Stop-Motion for Winding-Machines, of which the following is a full, clear, and exact specification.

In machines for winding thread upon cones it frequently happens that the thread gets beyond the large end of the cone and becomes wound upon the actuating spindle, thereby entailing loss of time in untangling the snarl, as well as of valuable material.

The object of this invention is the construction of an attachment to a well known type of cone winder, by means of which the machine will be automatically stopped as soon as the thread begins to get beyond the end of the cone.

Referring to the drawings forming part of this specification, Figure 1 is a perspective View of parts of a well known form of cone winder showing my attachment applied thereto. Fig. 2 is an elevation of parts of the same. Fig. 3 is a plan view of a plate carrying certain operative portions of my attachment.

The parts indicated in the drawings as those of a well known form of winding machine, comprise portions of the frame 1, the traverse frame 2 oscillative on an axis concentric with the stopping lever wheel 3, the frame 2 having a counterweight 4. Pivotally supported on the traverse frame dog segment 5 is the stopping lever 6 whose extremity 7 is normally supported close to the periphery of the stopping lever wheel 3. The normal support is the yarn being fed to the cone 9, and the operation is such that when the yarn breaks, the lever extremity swings against the periphery of the wheel 3 and the cogs 10 thereof strike the lever extremity 7 with such force as to communicate an upward throw to the segment 5, and thereby to unclutch the cone from the driving mechanism, and at the same time to apply a braking action to the rotation of the cone in the well known mannor in which these machines are constructed.

My attachment to this winding machine comprises a lever 11 pivotally supported at 12 to swing both axially and radially with respect to the cone 9. The pivotal support shown in Fig. 2 is more clear in construction than that illustrated in Fig. 1, the helical section 23 of the stopping lever 6.

When the latch 16 is pressed back by a lateral push given to the lever 11, the bar 17 is released and springs inward, thereby giving a corresponding push to the stopping leverh, the bar acting through the arm 20. This action on the stopping lever puts it into engagement with the cogs 10 and there by stops the actuation of the cone 9 in the manner already referred to.

A light spring 25 in the housing 24 serves to keep the latch 16 in secure normal control of the bar 17, and the nose 15 is tapered to permit the tubular connector 14: to oscillate with the lever 11 as the latter is given a swing in a radial direction relative to the cone. This radial swing has for its object to permit the lever to be withdrawn from the cone when the traverse frame 2 is moved away from the cone. To perform this automatically, I connect the frame 2 with the lever 11 by a wire 26, by means of which the lever will swing away from engagement with the cone simultaneously with the traverse frame.

By means of this attachment, if the yarn should begin to wind upon the cone-mandrel beyond the designated base of the cone, the yarn would press against the lever 11 and thereby release the bar 17 and stop further winding until the yarn is properly placed, and the bar 17 reset.

As shown in the drawings, this attachment can be readily applied to an existing winding machine of the type specified.

What I claim is:

l. The combination with a winding machine having an automatic stop motion, of a member yieldingly pressed in an axial direction against an end of the material being wound, and means connected with said automatic stop whereby an axial displacement of said member will actuate said automatic stop.

2. The combination with a winding ma normally helc inactive by said latch, the

latter being adapted to release said springactuated devlce when said member 18 dlsplaced.

3. The combination with a winding machine having an automatic stopping device, of a pivotally supported lever disposed for resting against the end of the material being wound, and means connected with said stopping device and controlled by said lever whereby the displacement of said lever actuates said stopping device.

4:. The combination with a winding device having an oscillating traverse frame and an automatic stopping device, of, a pivotally supported lever disposed for resting against the end of the material being wound,

means connected with said stopping device and controlled by said lever whereby the displacement of said lever actuates said stopping device, and a connection between said frame and lever whereby the two swing in unison to and from the work.

5. The combination with a winding device having an automatic stopping device and supporting means, of a plate held by said supporting means, a bar slidably supported by said plate, a latch carried by said plate for holding said bar in a set position, a spring acting on said bar, a member resting in contact with an end of the material being wound, and connection between said member and latch whereby the displacement of said member causes the latch to release said bar and the stopping device to be actuated.

In testimony that I claim the foregoing invention, I have hereunto set my hand this 14th day of January 1920.
